EPHRAIM WIMER, OF ORABBOTTOM, VIRGINIA.

SASH-LOGK.

To all whom it may concern:

Be it known that I, EPHRAIM WIMER, a citizen of the United States,residing at Crabbottom, in the county of Highland and State of Virginia,have invented a new and useful Sash-Lock, of which the following is aspecification.

The invention relates to improvements in sash looks.

The object of the present invention is to improve the construction ofsash locks, and to provide a simple, inexpensive and efficient one ofgreat strength and durability, adapted to be readily applied to a windowand capable of securely looking a sash in its closed position and atvarious adjustments, and of effectually preventing the sash from beingraised from the exterior.

With these and other objects in view, the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawing, and pointed out in the claimhereto appended; it being understood that various changes in the form,proportion, size and minor details of construction, within the scope ofthe claim, may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In the drawing :Figure 1 is a perspective view of a sash lock,constructed in accordance with this invention and shown applied to aportion of a window. Fig. 2 is a horizontal sectional view of the same.Fig. 3 is a vertical sectional view of the sash lock.

Like numerals of reference designate corresponding parts in all thefigures of the drawing.

The window sash 1 is equipped with a vertical keeper bar 2, adapted tobe engaged by a horizontally swinging locking arm 3, hinged to a plate 4by a pintle 5. The plate 4 is pierced by screws 6, or other suitablefastoning devices for securing the plate to the window frame 7, asclearly shown in Fig. 1 of the drawing. The said plate is provided atits inner edge with vertically alined eyes 8, and the locking arm has asimilar eye 9 at its inner end. The eye 9 of the locking arm is arrangedbetween the upper and lower eyes 8 of the plate, and is secured to thelatter by means of the vertical pintle 5, which passes through the saideyes. The locking arm is Specification of Letters Patent.

adapted to swing horizontally to engage it with and disengage it fromthe keeper bar 2.

The keeper bar 2, which is secured by screws 10, or other suitablefastening devices. to the sash at one side thereof, is designed inpractice to be about twenty inches in length, more or less, and it isprovided at intervals of two inches, or thereabout, with recesses 11.The recesses, which extend across the keeper bar, are adapted to receivethe looking arm 3, and have horizontal lower walls. The upper walls ofthe recesses are provided with grooves 12, adapted to receive the upperedge of the locking arm, which after being swung into a recess, isengaged with the top groove by a slight downward movement of the sash.This will prevent the locking arm from being swung outward before beingdis engaged from the upper wall of the sash. By this construction, therewill be no liability of the sash lock being accidentally unfastened bysmall children. The locking arm extends beyond the keeper bar, when inengagement with the same, and is equipped at its free end with a knob13, or other suitable means for enabling the locking bar to be readilyoper ated.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

A sash lock comprising a keeper bar pro vided at intervals withhorizontal recesses having grooves in their upper walls, a plateprovided at its inner edge with vertically alined spaced eyes, a pintlearranged in the eyes, and a horizontally swinging locking arm providedat one end with an eye arranged between the said eyes and hinged to theplate by the said pintle, said locking arm being arranged to swing intoand out of the recesses of the keeper bar and adapted to be engaged withthe grooves at the tops of the recesses by a slight downward movement of.the sash, whereby the locking arm and the keeper bar are interlocked tohold the former against outward movement.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.

EPHRAIM WIMER.
